The United Mexican States[5] (Spanish: Estados Unidos Mexicanos?·i), commonly known as Mexico (IPA: /ˈmɛksɪkoʊ/) (Spanish: México?·i IPA: ['mexiko]), is a federal constitutional republic in North America. It is bordered on the north by the United States; on the south and west by the North Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico.[6][7] The United Mexican States are a federation comprising thirty-one states and a federal district, the capital Mexico City, whose metropolitan area is one of the world's most populous.

Covering almost 2 million square kilometres,[8] Mexico is the fifth-largest country in the Americas by total area and the 14th largest independent nation in the world. With an estimated population of 109 million,[9] it is the 11th most populous country and the most populous Spanish-speaking country in the world.

As a regional power[10][11] and the only Latin American member of the Organisation for Economic Co-operation and Development (OECD) since 1994, Mexico is firmly established as an upper middle-income country.[12]

Mexico is a newly industrialized country[13][14][15][16] and the 12th largest economy in the world by GDP by purchasing power parity. The economy is strongly linked to those of its North American Free Trade Agreement (NAFTA) partners. Despite being considered an emerging power,[17] the uneven distribution of income and the increase in insecurity are issues of concern.

Elections held in July 2000 marked the first time that an opposition party won the presidency from the Institutional Revolutionary Party (Spanish: Partido Revolucionario Institucional, PRI) which had held it since 1929, culminating the political alternation at the federal level, which had begun at the local level during the 1980s.

Etymology

Main article: Toponymy of Mexico

After New Spain won independence from Spain, it was decided that the new country would be named after its capital, Mexico City, which was founded in 1524 on top of the ancient Aztec capital of México-Tenochtitlan. The origin of the name of the city comes from the Nahuatl language, where Mextli or Mēxihtli, a secret name for the god of war and patron of the Aztecs, Huitzilopochtli, in which case Mēxihco means "Place where Mēxihtli lives". Another hypothesis is that the word Mēxihco derives from the mētztli ("moon"), xictli ("navel", "center" or "son"), and the suffix -co (place), in which case it means "Place at the center of the moon" or "Place at the center of the Lake Moon", in reference to Lake Texcoco. The system of interconnected lakes, of which Texcoco was at the center, had the form of a rabbit, the same image that the Aztecs saw in the moon. Tenochtitlan was located at the center (or navel) of the lake (or rabbit/moon).[18] Still another hypothesis suggests that it is derived from Mēctli, the goddess of maguey.

The name of the city was transliterated to Spanish as México with the phonetic value of the x in Medieval Spanish, which represented the voiceless postalveolar fricative /ʃ/. This sound, as well as the voiced postalveolar fricative /ʒ/, represented by a j, evolved into a voiceless velar fricative /x/ during the sixteenth century.[19] This led to the use of the variant Méjico in many publications in Spanish, most notably in Spain, whereas in Mexico and some other Spanish–speaking countries México was the preferred spelling. In recent years the Real Academia Española, which regulates the Spanish language, determined that both variants are acceptable in Spanish but that the normative recommended spelling is México.[20] The majority of publications in all Spanish-speaking countries now adhere to the new norm, even though the alternative variant is still occasionally used.[21] In English, the x in Mexico represents neither the original nor the current sound, but the consonant cluster /ks/. The name of the country has had slightly changes since its creation, starting as the First Mexican Empire proceed by the Second Mexican Empire then the Mexican Republic and finally as the United Mexican States.[18]

History

Main article: History of Mexico

Pre-Columbian civilizations

Archaeological sites of Chichén-Itzá, one of the New Seven Wonders.

Human presence in Mesoamerica was once thought to date back 40,000 years based upon what were believed to be ancient human footprints discovered in the Valley of Mexico, but after further investigation using radiometric dating, it appears this is untrue.[22] It is currently unclear whether 21,000 year old campfire remains found in the Valley of Mexico are the earliest human remains found in the region.[23] For thousands of years, Mesoamerica was a land of hunter-gatherers. Around 9,000 years ago, ancient indigenous peoples domesticated corn and initiated an agricultural revolution, leading to the formation of many complex civilizations.

These civilizations revolved around cities with writing, monumental architecture, astronomical studies, mathematics, and large militaries. For almost three thousand years, Aridoamerica[24] and Mesoamerica[25] were the site of several advanced Amerindian civilizations.

In 1519, the native civilizations of Mesoamerica were invaded by Spain;[26] among them the Aztecs, Mayans, etc. This was one of the most important conquest campaigns in America. Two years later, in 1521, the Aztec capital of Tenochtitlan was conquered by the Spaniards along with the Tlaxcaltecs, the main enemies of the Aztecs, marking the end of the Aztec and giving rise to the Viceroyalty of New Spain in 1535. It became the first and largest provider of resources for the Spanish Empire and the most populous of all Spanish colonies.

Colonial era and independence

Almost 300 years after New Spain was created, on September 16, 1810, independence from Spain was declared by Priest Miguel Hidalgo y Costilla, in the small town of Dolores, Guanajuato.[27] This was the catalyst for a long war that ended in 1821 which eventually led to the independence and creation of the ephemeral First Mexican Empire. The Empire's territory encompassed the area of the current Mexican republic as well as the present-day U.S. states of California, Nevada, Utah, Arizona, New Mexico, Texas, parts of Colorado and Wyoming, and all current Central American countries except for Panama and Belize. Agustín de Iturbide was the first and only emperor. Two years later, he was deposed by the republican forces. The Central American states separated, forming the Federal Republic of Central America. In 1824, a republican constitution was drafted creating the United Mexican States with Guadalupe Victoria as its first President.

The first four decades after the creation of the country were marked by a constant strife between liberales (those who supported the federal form of government stipulated in the 1824 constitution) and conservadores (who proposed a hierarchical form of government in which all local authorities were appointed and subject to a central authority).[28] General Antonio López de Santa Anna was a strong influence in Mexican politics, a centralist and a two-time dictator. In 1836, he approved the Siete Leyes, a radical amendment to the constitution that institutionalized the centralized form of government. Having suspended the Constitution of 1824, civil war spread across the country, and three new governments declared independence; the Republic of Texas, the Republic of the Rio Grande (recognized by the United Kingdom) and the Republic of Yucatán. Only Texas was able to defeat Santa Anna, and later the annexation of Texas by the United States created a border dispute that would cause the Mexican–American War. Santa Anna played a big role in trying to muster Mexican forces but this war resulted in the resolute defeat of Mexico and as a result of the Treaty of Guadalupe Hidalgo (1848), Mexico lost one third of its surface area due to civil war with Texas, and later war with the United States.

Dissatisfaction with Santa Anna's return to power, and his unconstitutional rule, led to the liberal Plan of Ayutla, which initiated an era of liberal reforms, known as La Reforma, after which a new constitution was drafted that reestablished federalism as the form of government and first introduced freedom of religion. In the 1860s the country again underwent a military occupation, this time by France, which established the Habsburg Archduke Ferdinand Maximilian of Austria on the Mexican throne as Emperor Maximilian I of Mexico with support from the Catholic clergy and the conservative Mexicans. This Second Mexican Empire was victorious for only a few years, when the previous president of the Republic, the Zapotec Indian Benito Juárez, managed to restore the republic in 1867.

20th and 21st centuries

Evolution of the Mexican territory.

Porfirio Díaz, a republican general during the French intervention, ruled Mexico from 1876–1880 and then from 1880–1911 in five consecutive reelections. The period of his rule is known as the Porfiriato, which was characterized by remarkable economic achievements, investments in art and sciences, but also of huge economic inequality and political repression.[29] A likely electoral fraud that led to his fifth reelection sparked the Mexican Revolution of 1910, initially led by Francisco I. Madero. Díaz resigned in 1911 and Madero was elected president but overthrown and murdered in a coup d'état in 1913 led by a conservative general named Victoriano Huerta.This re-ignited the civil war, with participants such as Pancho Villa and Emiliano Zapata who formed their own forces. A third force, the constitutional army led by Venustiano Carranza, managed to bring an end to the war, and radically amended the 1857 Constitution to include many of the social premises and demands of the revolutionaries into what was eventually called the 1917 Constitution. Carranza was killed in 1920 and succeeded by another revolutionary hero, Álvaro Obregón, who in turn was succeeded by Plutarco Elías Calles. Obregón was reelected in 1928 but assassinated before he could assume power. In 1929, Calles founded the National Revolutionary Party (PNR), later renamed the Institutional Revolutionary Party (PRI) which became the most influential party during the next 70 years.

Between 1940 and 1980, Mexico experienced substantial economic growth that some historians call "El Milagro Mexicano", the Mexican Miracle.[30] The assumption of mineral rights by the government, and the subsequent nationalization of the oil industry into PEMEX during the presidency of Lázaro Cárdenas (1938) was a popular move, but sparked a diplomatic crisis with those countries whose citizens had lost businesses expropriated by the Cárdenas government.

Although the economy continued to flourish, social inequality remained a factor of discontent. Moreover, the PRI rule became increasingly authoritarian and at times oppressive.[31] An example of this is the Tlatelolco massacre[32] of 1968, which according to government officials claimed the life of around 30 protesters, while conservative estimates state that at least 300 were killed and others estimate as many as 800 died.[33]

In the 1970s there was extreme dissatisfaction with the administration of Luis Echeverría which took missteps in both the national and international arenas. Nonetheless, it was in this decade that the first substantial changes to electoral law were made, which initiated a movement of democratization of a system that had become electorally authoritarian.[34][35] While the prices of oil were at historically high records and interest rates were low, Mexico made impressive investments in the state-owned oil company, with the intention of revitalizing the economy, but overborrowing and mismanagement of oil revenues led to inflation and exacerbated the crisis of 1982. That year, oil prices plunged, interest rates soared, and the government defaulted on its debt. In an attempt to stabilize the current account balance, and given the reluctance of international lenders to return to Mexico given the previous default, President de la Madrid resorted to currency devaluations which in turn sparked inflation.

The first small cracks in the political monopolistic position of PRI were seen in the late 1970s with the creation of 100 deputy seats in the Chamber of Deputies assigned through proportional representation with closed party-lists. Even though at the municipal level the first non-PRI mayor was elected in 1947,[36] it was not until 1989 that the first non-PRI governor of a state was elected (Ernesto Ruffo Appel in Baja California). However, many sources claimed that in 1988 the party resorted to electoral fraud in order to prevent leftist opposition candidate Cuauhtémoc Cárdenas from winning the national presidential elections who lost to Carlos Salinas de Gortari, which led to massive protests in the capital.[37] Salinas embarked on a program of neoliberal reforms which fixed the exchange rate, controlled inflation and culminated with the signing of the North American Free Trade Agreement (NAFTA), which came into effect in 1994. However, that very same day, the Zapatista Army of National Liberation (EZLN) started a two-week-lived armed rebellion against the federal government, and has continued as a non-violent opposition movement against neoliberalism and globalization. Being an election year, in a process that was then called the most transparent in Mexican history, authorities were reluctant to devalue the peso, a move which caused a rapid depletion of the National Reserves. In December 1994, a month after Salinas was succeeded by Ernesto Zedillo, the Mexican economy collapsed.

With a rapid rescue packaged authorized by United States President Bill Clinton and major macroeconomic reforms started by president Zedillo, the economy rapidly recovered and growth peaked at almost 7% by the end of 1999.[38] After a comprehensive electoral reform to increase party representation during Zedillo's administration, as well as discontent with PRI after the economic crisis, led the PRI to lose its absolute majority in the Congress in 1997. In 2000, after 71 years the PRI lost a presidential election to Vicente Fox of the opposition National Action Party (PAN). Neither party had absolute majority in the Congress.

On March 23, 2005, the Security and Prosperity Partnership of North America was signed by Vicente Fox. During the 2006 elections, the position of the PRI in the Congress was further weakened and became the third political force in number of seats in the Chamber of Deputies after the PAN and the Party of the Democratic Revolution (PRD), even though the party still has the plurality of state governorships. In the concurrent presidential elections, Felipe Calderón from the PAN was declared the winner, with a razor-thin margin over Andrés Manuel López Obrador of the PRD. López Obrador, however, contested the election and pledged to create an "alternative government".[39]

Government and politics

Main article: Politics of Mexico

Mexican Congress.

The United Mexican States are a federation whose government is representative, democratic and republican based on a presidential system according to the 1917 Constitution. The constitution establishes three levels of government: the federal Union, the state governments and the municipal governments. All officials at the three levels are elected by voters through first-past-the-post plurality, proportional representation or are appointed by other elected officials.

The federal government is constituted by the Powers of the Union, the three separate branches of government:

All elected executive officials are elected by plurality (first-past-the-post). Seats to the legislature are elected by plurality and proportional representation at the federal and state level.[43] The Chamber of Deputies of the Congress of the Union is conformed by 300 deputies elected by plurality and 200 deputies by proportional representation with closed party lists[44] for which the country is divided into 5 electoral constituencies or circumscriptions.[45] The Senate is conformed by a total of 128 senators: 64 senators, two per state and the Federal District elected by plurality in pairs; 32 senators assigned to the first minority or first-runner up (one per state and the Federal District), and 32 elected by proportional representation with closed party lists for which the country conforms a single electoral constituency.[44]

According to the constitution, all constituent states must have a republican form of government composed of three branches: the executive, represented by a governor and an appointed cabinet, the legislative branch constituted by a unicameral congress and the judiciary, also called a Supreme Court of Justice. They also have their own civil and judicial codes.

In the 2006–2009 Congress of the Union, eight parties are therein represented; five of them, however, have not received neither in this nor in previous congresses more than 4% of the national votes.[46] The other three parties have historically been the dominant parties in Mexican politics:

The PRI held an almost hegemonic power in Mexican politics since 1929. Since 1977 consecutive electoral reforms allowed opposition parties to win more posts at the local and federal level. This process culminated in the 2000 presidential elections in which Vicente Fox, candidate of the PAN, became the first non-PRI president to be elected in 71 years.

In 2006, Felipe Calderón of the PAN faced Andrés Manuel López Obrador of the PRD in a very close election (0.58% difference), in a system without a second-ballot. On September 6, 2006, Felipe Calderón was declared President-elect by the electoral tribunal. His cabinet was sworn in at midnight on December 1, 2006 and Calderón was handed the presidential sash by outgoing Vicente Fox at Los Pinos. He was officially sworn as President on the morning of December 1, 2006 in Congress.

Main article: Foreign relations of Mexico

Traditionally, the Mexican government has sought to maintain its interests abroad and project its influence largely through moral persuasion rather than through political or economical pressure.

Since the Mexican Revolution, and until the administration of President Ernesto Zedillo, Mexico had been known for its foreign policy or "doctrine" known as the Doctrina Estrada ("Estrada Doctrine", named after its creator Genaro Estrada). The Estrada Doctrine was a foreign policy guideline of an enclosed view of sovereignty. It claimed that foreign governments should not judge, positively or negatively, the governments or changes in government of other nations, in that such action would imply a breach to their sovereignty.[47] This policy was said to be based on the principles of Non-Intervention, Pacific Solution to Controversies, and Self-Determination of all nations.

During his presidency, Vicente Fox appointed Jorge Castañeda to be his Secretary of Foreign Affairs. Castañeda immediately broke with the Estrada Doctrine, promoting what was called by critics the "Castañeda Doctrine".[48] The new foreign policy called for an openness and an acceptance of criticism from the international community, and the increase of Mexican involvement in foreign affairs.[49]

In line with this new openness in Mexico's foreign policy, some political parties have proposed an amendment of the Constitution in order to allow the Mexican Army, Air Force or Navy to collaborate with the United Nations in peace-keeping missions, or to provide military help to countries that officially ask for it.

Military

Main articles: Military of Mexico, Mexican Army, Mexican Air Force, and Mexican Navy

Mexico has the second largest defense budget in Latin America, with annual military expenditures of US$6 billion or about 0.5% GDP.[50] Mexico's military includes 503,777 total personnel, of which around 192,770 are active in the frontline.[51][52] Since the 1990s, when the military escalated its role in the war on drugs, increasing importance has been placed on acquiring airborne surveillance platforms, light aircraft, helicopters and rapid troop transport.[53][54] The Mexican Military has two branches: the Mexican Army (which includes the Mexican Air Force), and the Mexican Navy. The Mexican armed forces maintain significant infrastructure, including small electronics and weapons testing and research facilities,[55]weapons and vehicle manufacturing centers, and naval dockyards that have the capability of building heavy military vessels.[56] These dockyards and facilities have a significant employment and economic impact in the local economies. In recent years, due in part to its military modernization program, Mexico has improved its training techniques, military command and information structures and has taken steps to becoming more self-reliant in supplying its military by designing as well as manufacturing its own guns,[57] missiles,[58] unmanned air vehicles[59] and naval ships.[60]

Army

There are three main components of the Mexican Army: a national headquarters, territorial commands, and independent units. The Minister of Defense commands the Army by means of a very centralized system and a large number of general officers. The Army uses a modified continental staff system in its headquarters. The Army is the largest branch of Mexico's armed services. At present there are 12 'Military Regions', which are further broken down into 44 subordinate 'Military Zones'.

Air Force

The Mexican Air Force is part of the Mexican Army. The national headquarters is embedded in the Army headquarters in Mexico City. It also follows the continental staff system, with the usual A1, A2, A3, and A4 sections. The tactical forces form what is loosely called an Air Division, but it is dispersed in four regions—Northeast, Northwest, Central, and Southern. The Air Force maintains a total of 18 air bases, and has the additional capability of opening temporary forward operating bases in austere conditions for some of the rotary wing and light fixed-wing assets.

Navy

The Ministry of the Navy, the Mexican Navy’s national headquarters, is located in Veracruz City. The “Junta (or Council) of Admirals” plays a unique consultative and advisory role within the headquarters, an indication of the institutional importance placed on seniority and “year groups” that go back to the admirals’ days as cadets in the naval college. They are a very tightly knit group, and great importance is placed on consultation among the factions within these year groups.

The Navy’s operational forces are organized as two independent groups: the Gulf (East) Force and the Pacific (West) Force. Each group has its own headquarters, a destroyer group, an auxiliary vessel group, a Marine Infantry Group, and a Special Forces group. The Navy also has an air arm with troop transport, reconnaissance, and surveillance aircraft.

Law enforcement and crime

Mexican federal police.

Public security is enacted at the three levels of government, each of which has different prerogatives and responsibilities. Local and state police department are primarily in charge of law enforcement, whereas the Federal Preventive Police is in charge of specialized duties. All levels report to the Secretaría de Seguridad Pública (Secretariat of Public Security). The General Attorney's Office (Procuraduría General de la República, PGR) is the executive power's agency in charge of investigating and prosecuting crimes at the federal level, mainly those related to drug and arms trafficking, espionage, and bank robberies.[61] The PGR operates the Federal Investigations Agency (Agencia Federal de Investigación, AFI) an investigative and preventive agency.[62]

While the government respects the human rights of most citizens,[63] serious abuses of power have been reported in security operations in indigenous communities and poor urban neighborhoods.[63] The National Human Rights Commission, however, has had little impact in reversing this trend, engaging mostly in documentation but failing to use its powers to issue public condemnations to the officials who ignore its recommendations.[64] By law, all defendants have the rights that assure them fair trials and human treatment; however, the system is overburdened and overwhelmed with several problems.[65] Despite the efforts of the authorities to fight crime and fraud, few Mexicans have strong confidence in the police or the judicial system, and therefore, few crimes are actually reported by the citizens.[65] In 2008, president Calderón proposed a major reform of the judicial system, which was approved by the Congress of the Union, which included oral trials, the presumption of innocence for defendants, the authority of local police to investigate crime—until then a prerogative of special police units—and several other changes intended to speed up trials.[66]

Total crimes per capita average 12 per 1,000 people in Mexico, ranking 39 in a survey of 60 countries.[67] Violent crime is a critical issue in Mexico; with a rate of homicide varying from 11 to 14 per 100,000 inhabitants.[68] Drug-traffic and narco-related activities are a major concern in Mexico. Drug cartels are active in the shared border with the US and police corruption and collusion with drug cartels is a crucial problem.[68] Current president Felipe Calderón made abating drug-trafficking one of the top priorities of his administration. In a very controversial move, Calderón deployed military personnel to cities where drug cartels operate. While this move has been criticized by the opposition parties and the National Human Rights Commission, its effects have been praised by the Bureau for International Narcotics and Law Enforcement Affairs as having obtained "unprecedented results..." with "many important successes".[69] In October 2007, the president Calderón and US president George W. Bush announced the Mérida Initiative a historic plan of law enforcement cooperation between the two countries.[70]

The federation: States of Mexico and the Federal District

Main articles: Political divisions of Mexico and Mexican state name etymologies

The United Mexican States are a federation of thirty-one free and sovereign states which form a Union that exercises jurisdiction over the Federal District and other territories. Each state has its own constitution and congress, as well as a judiciary, and its citizens elect by direct voting, a governor (gobernador) for a six-year term, as well as representatives (diputados locales) to their respective state congresses, for three-year terms.[71] The 31 states and the Federal District are collectively called "federal entities", and all are equally represented in the Congress of the Union.

Mexican states are also divided into municipalities (municipios), the smallest official political entity in the country, governed by a mayor or "municipal president" (presidente municipal), elected by its residents by plurality.[72] Municipalities can be further subdivided into non-autonomous boroughs or in semi-autonomous auxiliary presidencies.

Constitutionally, Mexico City, as the capital of the federation and seat of the powers of the Union, is the Federal District, a special political division in Mexico that belongs to the federation as a whole and not to a particular state, and as such, has more limited local rule than the nation's states.[73] Nonetheless, since 1987 it has progressively gained a greater degree of autonomy, and residents now elect a head of government (Jefe de Gobierno) and representatives of a Legislative Assembly directly. Unlike the states, the Federal District does not have a constitution but a statute of government. Mexico City is conterminous and coextensive with the Federal District.

The names of the thirty-one states and the Federal district and their official postal abbreviations in parentheses are presented in the following table, along with the commonly used state flags:

Geography and climate

Main article: Geography of Mexico

Mexico is located at about 23° N and 102° W[74] in the southern portion of North America.[75][76] It is also located in a region known as Middle America.[77][78] Almost all of Mexico lies in the North American Plate, with small parts of the Baja California peninsula on the Pacific and Cocos Plates. Geophysically, some geographers include the territory east of the Isthmus of Tehuantepec (around 12% of the total) within Central America.[79] Geopolitically, however, Mexico is considered part of North America along with Canada and the United States.[80][81]

Mexico's total area is 1,972,550 km², making it the world's 14th largest country by total area, and includes approximately 6,000 km² of islands in the Pacific Ocean (including the remote Guadalupe Island and the Revillagigedo Islands), Gulf of Mexico, Caribbean Sea, and Gulf of California. On its north, Mexico shares a 3,141 km border with the United States. The meandering Río Bravo del Norte (known as the Rio Grande in the United States) defines the border from Ciudad Juárez east to the Gulf of Mexico. A series of natural and artificial markers delineate the United States-Mexican border west from Ciudad Juárez to the Pacific Ocean. On its south, Mexico shares an 871 km border with Guatemala and a 251 km border with Belize.

Topography

A field in the state of Jalisco.

Mexico is crossed from north to south by two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental, which are the extension of the Rocky Mountains from northern North America. From east to west at the center, the country is crossed by the Trans-Mexican Volcanic Belt also known as the Sierra Nevada. A fourth mountain range, the Sierra Madre del Sur, runs from Michoacán to Oaxaca. As such, the majority of the Mexican central and northern territories are located at high altitudes, and the highest elevations are found at the Trans-Mexican Volcanic Belt: Pico de Orizaba (5,700 m), Popocatépetl (5,462 m) and Iztaccíhuatl (5,286 m) and the Nevado de Toluca (4,577 m). Three major urban agglomerations are located in the valleys between these four elevations: Toluca, Greater Mexico City and Puebla.

Climate

Annual snowfall in Chihuahua, Chihuahua.
The Altar desert, Sonora.

The Tropic of Cancer effectively divides the country into temperate and tropical zones. Land north of the twenty-fourth parallel experiences cooler temperatures during the winter months. South of the twenty-fourth parallel, temperatures are fairly constant year round and vary solely as a function of elevation.This gives Mexico one of the world's most diverse weather systems in the world.

Areas south of the twenty-fourth parallel with elevations up to 1,000 meters (the southern parts of both coastal plains as well as the Yucatán Peninsula), have a yearly median temperature between 24 and 28 °C. Temperatures here remain high throughout the year, with only a 5 °C difference between winter and summer median temperatures. Although low-lying areas north of the twentieth-fourth parallel are hot and humid during the summer, they generally have lower yearly temperature averages (from 20 to 24 °C) because of more moderate conditions during the winter.

Many large cities in Mexico are located in the Valley of Mexico or in adjacent valleys with altitudes generally above 2,000 m, this gives them a year-round temperate climate with yearly temperature averages (from 16 to 18 °C) and cool nighttime temperatures throughout the year.

Many parts of Mexico, particularly the north, have a dry climate with sporadic rainfall while parts of the tropical lowlands in the south average more than 200 cm of annual precipitation.

Biodiversity

Mexico is one of the 18 megadiverse countries of the world. With over 200,000 different species, Mexico is home of 10–12% of the world's biodiversity.
